Although the nude ascent was intended as a specific tribute to Guy Edwards, my research has uncovered a rich history of BC nude speed ascents. The oldest being the second ascent of the West Lion, when Chief J Capilano sent "one of his braves, stripped naked for speed, to repeat the route... up and down in under 15 minutes" c. 1903.
I'm certain Lowell Skoog or Harry Majors can contribute a history of important Washington area naked ascents.
